thumping tappets

[sunny]

.........Brokedown this evening, (inevitable I suppose but annoying none the less)

Recovered the van back home, where I know its safe rather than at a garage.

First suspicions are that it could be 1 of 2 things, (maybe both), 1. Push rods 2. Big end bearings. Either way sounds like this is gonna cost alot of money

The engine has been running unbelievable today, (Well until this)

Can anyone advise me if this has ever happened to them and what the best cource of action would be?

Cheers

Steve

Might help if you actually tell us what happened???

[fullsunian]

Ive not got a clue what has happen, but the first thing I would do is take the rocker covers off and see what is going on in there.
I bought a van that had stood for years coz the engine had 'blown up' only to remove a rocker cover and find a valve adjuster and nut in the bottom of a cover. Sounded like a bag of nails too. Adjuster and nut back on..mint

Mmm

Could be the wurzel scrumage arm rebound spring........

Whats happened?
Who has determined its either the pushrods or big end bearings?

What ACTUALLY happened?

Been using the van today, nothing unusual. Stopped for some cans about 7 miles from home after a 50 ish mile drive around today. After less than a mile of stopping the van suddenly shuddered and became very loud, like a tappet noise. Coasted to a stop and had a look, scratched my head then decided to call the recovery, the guy arrived and said that it sounded like the big end bearings and then went off to get a flat bed to recover me. Another guy turned up and said that it could be the big end bearings or the push rods, I wounder if they got another guy it would have been the big end bearings, push rods and something else?

Anyway, got home, started first time, all be it noisey and parked it up on the drive.

Hope this helps you to help me.

Get them rocker covers off

[sunny]

I will do, I will have a look tomorrow evening and let you know. I need to get this sorted quick as I have a MOT on Thursday.

[sunny]

Not had a chance today to get rocker cover off, due to work and rain

I am really worried about this situation now, I have the recovery guys coming on Thursday to take the van to my garage for them to have a look at it. Any ideas what it could be or what it will cost. I know that these vans are a labour of love

I wanna save the engine? Are the possibilities of 1. Big end bearings 2. push rods 3. Loose tappet easy to repair?

Other points.....Engine was running very sweet up to the point of breakdown, no smoke, no loss of oil or oil pressure, slight loss of power but nothing much, everything looks very normal on the outside. Just very loud on the outside. If I could explain the noise it was the classic Aircooled noise with a set of very unadjusted tappets, sounds like as you look at the engine the right hand side?

Any help or ideas???

I have been under the van and had a look for any change from yesterday. I have noticed that there is a build up of oil, more than normal around the fuel pump which is located above a warm air duct under the right hand side of the engine, where the noise is coming from, I did notice yesterday that I could smell petrol fumes and wonder if this is something to do with it? Does this run off the crankshaft? I suspect it does. Could a worn pump cause this noise where its not alingned with the crank gearing, it sounds to loud to me, but maybe

Any ideas?

hmmm mine being a water pumper running sweet ,,then ohhh then oohh again like i hit a wall then bang and steam,smoke ,kids screaming were on fire .i no longer have drive am coasting ,,piston through main casing big hole bits of metal everywhere anyway i,ve found most of bits am gunna glue it back together an see what happens think mines called throwing a rod ,,growl was gunna get a nice picture up cant work it,,my bad

After breaking down at the weekend, the van van has sat idle for the past couple of days. Its being recovered into the garage today for them to have a look at it.

I have had a look myself, only change is there is a build up of oil around the oil pump (hasnt dripped). I havent started the van since, should I try and thinken the oil. I did an oil change in March and wonder if its not crude enough!! I have checked the oil and the level hasnt changed and its very clean.

Do you advice that I start the van or just get it to the garage.

Help....

Pretty normal

NO !!

Like the others have said, get the rocker covers off (this is a WBX engine I take it ?)

It is unlikely given what you have told us about this engine so far, that it is the big ends, they are pretty robust on these engines, (though I believe the 2.1 engine is more prone to failure here).

If you are not sure what to look for in the rocker covers, ask on here, or get someone who KNOWS about these engines to have a look for you (there maybe someone on here near to Milton Keynes that will pop over for the price of a few beers) Most average garages it seems cannot be trusted to get it right with these engines / vans !

The sweetest piece of prose that I have seen for some time!
What relevance here? (It may be but is so difficult to read that I can't be bothered)

[sunny]

The engine is a 2000cc CU Aircooled from a 1980 T25.

Have been having quotes all day for new engines, but I still believe in the old boy and think it something less drastic

Anyone around MK wanting to have a look in exchange for a BBQ and some beers your more than welcome

OK, Rocker covers came off today, checked all rockers on 4 cylinders, couple of rockers move, latteral rather than rocking, they are sat in what in the correct position. Nothing else loose, all bolts in the correct place.

Checked the oil, thats fine, so ran the engine, tappets I could hear and a undertone of a deeper noise?

What could it be?
